Celebrities boost auction sale totals - both on and off the saleblock... Here's how'

This week's Paul Fraser Collectibles newsletter is a bit of a 'celebrity-studded' special.

First came UK rapper Tinie Tempah's purchase of a limited edition pair of sneekers modelled on those worn by Marty McFly (played by Michael J Fox) in the time travel movie classic Back to the Future Part II.

Tempah paid $37,500 for his trainers (the 22-year-old would have only just been born around the time of the film's original 1989 release).

Coppola's Inglewood wine

All proceeds went to charity, and also won the star some publicity outside his native UK.

Hot on Tinie Tempah's heels was the legendary film director Francis Ford Coppola, the man behind the Godfather trilogy, Apocalypse Now and other classics.

Only it wasn't movie memorabilia in Mr Coppola's case, but instead fine wines from the Inglenook estate in the Napa Valley.

Since purchasing the property in 1975, Coppola has tirelessly reconstructed and restored the estate to its former glory. The sale of his wines contributed significantly to Christie's $1.8m auction total.
